I create a VM with PopOS and added as Graphics Card the Nvidea as you can see below: But if I connect the monitor to the graphics card notting happen, do I forgot something ?

HI JorgeB, just to confirm that all works now. I created the second pool for the VM. Thank a lot for your help .... you are the best 🙂 Grazie Claudio

done root@Tower:~# btrfs balance start -dusage=90 /mnt/cache Done, had to relocate 42 out of 318 chunks Can I go on with these steps ? next steps are : 1. stop array 2. remove the device 3. Start the array 4. stop array create you pool 5. assign the disk to the new pool tower-diagnostics-20220518-1703.zip

Ok I execute this command Ibtrfs balance start -dusage=75 /mnt/cache outcome: Overall: Device size: 931.52GiB Device allocated: 931.52GiB Device unallocated: 3.02MiB Device missing: 0.00B Used: 593.10GiB Free (estimated): 166.57GiB (min: 166.57GiB) Free (statfs, df): 166.57GiB Data ratio: 2.00 Metadata ratio: 2.00 Global reserve: 154.06MiB (used: 0.00B) Multiple profiles: no Data Metadata System Id Path RAID1 RAID1 RAID1 Unallocated -- -------------- --------- --------- --------- ----------- 1 /dev/sdb1 462.70GiB 3.00GiB 64.00MiB 1.99MiB 2 /dev/nvme0n1p1 462.70GiB 3.00GiB 64.00MiB 1.02MiB -- -------------- --------- --------- --------- ----------- Total 462.70GiB 3.00GiB 64.00MiB 3.02MiB Used 296.12GiB 434.41MiB 112.00KiB next steps are : 1. stop array 2. remove the device 3. Start the array 4. stop array create you pool 5. assign the disk to the new pool is it this way ? attached the diagnostics. tower-diagnostics-20220518-1530.zip

It works :-)))) I'm so happy thanks a lot . now If I want to remove a disk from the pool and use it as dedicated pool for the VM what do I have to do ? tower-diagnostics-20220518-1320.zip

these are error that I have in log of cache disk: ay 18 06:32:50 Tower kernel: BTRFS error (device sdb1): devid 2 uuid b7a2b6e5-effb-48f3-8fbe-34b212a45d2c is missing May 18 06:32:50 Tower kernel: BTRFS error (device sdb1): failed to read the system array: -2 May 18 06:32:50 Tower kernel: BTRFS error (device sdb1): open_ctree failed May 18 06:32:50 Tower root: mount: /mnt/cache: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error. Do you think that I lost all cache data ?

Hi JorgeB do you have an idea how I can fix the issues ? thanks
